CLOTH-SPREADING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 564,989, dated August4, 1896.

Application filed April 29, 1895. Renewed January 13, 1896. Serial No.575,390. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN GOLDENBERG, a citizen of the United States,residing in the city and count 7 of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Apparatus for Unrolling orSpreading Cloth or Similar Material Prior to Cutting, which improvementis fully set forth in the following specification and accompanyingdrawings.

My invention consists of novel details of construction, all as will behereinafter set forth.

Figure 1 represents a perspective view of an apparatus for unrollingcloth or similar material embodying my invention. Fig. 2 represents abroken front elevation of the same, showing another form of supportingdevices for the apparatus.

Similar letters of reference indicate corresponding parts in both thefigures.

Referring to the drawings, A designates a suitable bed upon which theapparatus is adapted to be mounted.

B designates abearing attached to said bed, in which is journaled theshaft of the gear C, the latter being provided with a crankhandle D.Said gear meshes with a pinion E, mounted. on the shaft F, which latterr0 tates in suitable bearings G on the said bed, said shaft F havingmounted thereon near its ends the sprocket-wheels H, which are engagedby the sprocket-chains J which pass around other sprocketwheels K at theother end of the bed, said wheels K being mounted on a suitable shaft L,which is journaled in the bearings M.

N designates posts or standards which may be composed of pipe-sections,if desired, one of said posts being on each side of the bed and, in thepresentinstance, inside the chains J, the latter having a connection Jextending therefrom to the said posts N.

P designates a foot or base portion which is attached to said post, andis provided with the rollers Q, which run or travel in or on the tracksR, which are arranged substan tially longitudinally of the bed A.

S designates cross-pieces which serve as a brace for said posts N, andwhich assist to guide the cloth as the same is unrolled, said posts Nbeing braced at their upper portion by means of the bar T, which isconnected to each post N.

U designates bearings which are attached to suitable portions of saidposts N, and have their tops open, whereby the shafts N can be readilyplaced therein, said shafts being prevented from lateral shifting bymeans of the collars X X on each end thereof. The said shafts W are eachprovided with a transversely-extending bar or rod Y, which has securednear its outer ends the forked pieces Z, portions of which engage theboard or central portion A of the roll of cloth A which is mountedthereon, said pieces Z having pivot-ally attached thereto the rods B,which are pivoted to each other and to the central substantiallyhorizontal rod C, whose free end enters the shaft W, which is preferablymade of tubing, said rod G being held in the desired position by meansof the setscrew D, whereby it will be seen that as the rod 0 is moved inor out of the shaft V the forked pieces Z will be caused to approach orrecede from each other, since they slide freely on the rods Y, and socan be readily adjusted to support rolls or bales of cloth or othermaterial of any size.

F designates a rod which is attached to,

the brackets G, which are mounted on said posts N, the function of saidrod F being to hold that portion of the material which is being unrolledfrom the upper bale out of contact with the revolving roll which isbelow, as will be explained.

H designates clamps which are suitably attached to the bed A, and whichhave a projecting finger J, whose end L is adapted to engage the clothas it is unrolled and hold the same in fixed position, as will beevident, said fingers being held in the desired position by the nuts K.

The operation is as follows: The crankhandle D being rotated, theengagement of the gear and pinion C and E will cause the sprocket-chainsJ to move either to the rightor to the left, and by reason of theconnection 3 between the posts N and said chains, the said posts will becaused to travel either to the right or to the left, as desired, and itwill thus be seen that if the free end of one or both of the rolls ofthe material A be attached to a fixed point, as N, and the posts N movedaway therefrom, the said material will be readily unwound, and when thesame has reached the extreme left of the bed by inserting the fingers Ltherein and holding the same rigidly in place by tightening the nut Kthe cloth will be held at that end of the board, and if now the posts Nare caused to travel to the right another length or layer of the clothwill be unwound, and so on until all the cloth is unwound from therolls, the clamping or holding devices being readily adj usted to rollsof diiferent sizes by loosening the set-screws D and moving the rods 0'in or out of the shafts IV, as is evident, and said shafts WV can bereadily inserted in their bearings U, as will be evident, the rod Fserving to hold the material of the upper roll out of contact with thelower roll as thesame is unwound, while the rod S serves to hold thecloth from both rollsin proper position while it is being unwound, saidrods S, F, andT serving also to brace the posts orstandards N, as is.evident, the material being thus unwound-and superimposed upon the tablein layers ready for cutting.

Itwill be evident that power may be ap plied to the I shafts F and L inany suitable manner and that various changes may be made in the mannerof assembling the differout parts of the above apparatus, which willcome Within the scope of my invention, and I do not, therefore, desireto be limited in every instance to the exact constructions I have hereinshown and described.

In Fig. 2 I have shown another form of supporting devices for the rollor bale of cloth, A designating the cloth, as before; Z, one of theforked pieces supporting the same; B O, the adjusting devices; W, theshaft, and N one of the posts or standards in which said shaft ismounted. 'lhestandN has a foot A"- attached thereto, which rests uponthe portion 13 of the block C the parts being held "in position by meansof a suitable thumbscrew D or similar device which passes through slotsin said portions A andB The lower portion of said block C has journaledtherein a roller D which is adapted to contact with the top of the tableE said block having a depending slotted arm F against which is heldtheslotted arm G", which has,

the extension H attached thereto, inwhich is .journaled the roller Jwhich contacts with the under side of the table E the parts F and Gbeingheld in position by means of the thumb-screws K the block 0 beingsuitably braced by means of the rod L It will thus beapparent from Fig.2 that the posts N can be readily moved toward or away from each other,in order to adjust the apparatus to rolls of cloth of varying widths,and the rollers D and J 3 can bemoved toward or away from each other toaccommodate tables of different thicknesses. Y

I desire to call especial attention to the adjustable attachment wherebythe cloth is enabled to be sustained in a central position,

said attachment being capable of adaptation to rolls of varying sizes.

It will be evident from the foregoing that a very effective andefficient machine is thus obtained which is especially useful forspreading or unrolling cloth, goods, or similar material upon a tableprior to cutting the same.

Having thus'described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a cloth-spreading apparatus, theposts N a shaft WV j ournaled on each of said posts, atransversely-extending rod connected with each of said shafts, theforked pieces Z movable on said rods, the rods 0 guided on said shafts,and the braces B pivoted to said forking piecesand to said rodsjO, saidparts being combined substantially as described.

2. In a cloth-spreading device a bed, the posts I each having a slottedfoot A the block C havingthe roller D bearing on said bed, the slottedportion B connected with said foot A the thumb-screw D and the dependingslotted arm F the-slottedarm G carrying the roller J bearing against theurn der side of the said bed and the thumb-screw K said parts beingcombined substantially as described.

3. In a cloth-spreading apparatus,:a bed, posts adapted to support rollsof cloth thereon, having laterally-extending feet, blocks on which-saidfeet aresupported, means foradjusting said feet and blocks relative toeach other, rollers journaled in said blocks, adapted to contact withthe top of said bed, and arms F adjustable relative to said blocks, eachof said arms having an extension thereon and a roller j ournaled in saidextension, and adapted to contact'with the under side of said bed,substantially as described.

4. In a cloth-spreading apparatus, a bed, posts supported thereupon,shafts journaled on-said posts, cloth-holding devicesmounted onsaidshafts, blocks-having rollers journaled therein and adapted to contactwith said: bed, means for connecting said blocks with said osts armshavin extensions thereon connected to said blocks, and rollers journaledinsaid extensions also adapted to contact with said bed, substantiallyas described.
